My previous system was very similar to yours, but with a Radeon HD5850 1GB instead of a GeForce. I upgraded before the last official patch which did bring some performance loss, so these settings may have had to have been reduced for acceptable performance. However, the current Beta may allow you to turn them up again. I don’t think that 1GB of VRAM will be too limiting with the resolution you are using.
